Sugoi Otaku's manga / #tragedy(5)

Tbh, I still don't get the ending. But Reading it was worthwhile. I don't get the ending at all. But the extra chapter in the end kinda gives hope. Idk. Really a bittersweet feeling after finishing reading this one. Did I say the ending is really ambiguous ? Give it a read, it's short

Man what a roller coaster ride. I feel bad for Doctor Ai though. A pure soul through and through. Zhinshu realised that him staying with doc would only bring him pain after he's gone, so he makes him promise to take care of himself. Damn
